Bell Weight, 2oz

Hello Dirt diggers and Electromagnetism mavericks, please look upon this image of a bell shaped Brass dongle found in Victorian central highlands, on the alleged site of Ye Olde Butcher Shoppe.
Suspected as being the lost part of a set of Weights, my specific question is about the markings on the left. Can they be an indication of the year the weight was issued? The opposing side has the vic+crown stamp duplicated on both sides.
Thanking the think tank in advance,
TheFoxintheBox.
